Asthma When our sons were playing hockey as children, my wife got talking with another hockey mom, who said her son had to use a “puffer” for his asthma. After we got her a zapper, and he started using it, he no longer needed his puffer. I told this to another friend, and he said “OK, I’ll have to give that zapper another try!” I am waiting for his response after having tried it again. It is interesting that Jesus told his followers “Let it be to you according to your faith.” If we don’t believe something, we won’t try it thoroughly, and so we won’t get the benefit of it.
